Method, device and system for controlling cable television system

Abstract

Disclosed are a method, a device and a system for controlling a cable television system. The method includes that: an intelligent mobile terminal detects whether the intelligent mobile terminal is connected to a home wireless network, and when it is detected that the intelligent mobile terminal is connected to the home wireless network, transmits a set-top box turn-on signal to a set-top box through the home wireless network; the set-top box executes a turn-on operation according to the received set-top box turn-on signal and transmits a television turn-on signal to a television. According to the disclosure, after a user of the intelligent mobile terminal gets home, the intelligent mobile terminal carried by the user automatically turns on the set-top box and the television, and the user does not need to use a remote controller of the set-top box and a remote controller of the television.

What is claimed is: 
     
       1. A method for controlling a cable television system, comprising:
 detecting, by an intelligent mobile terminal, whether the intelligent mobile terminal is connected to a home wireless network, and when it is detected that the intelligent mobile terminal is connected to the home wireless network, transmitting a set-top box turn-on signal to a set-top box through the home wireless network; and 
 performing, by the set-top box, a turn-on operation according to the received set-top box turn-on signal and transmitting a television turn-on signal to a television; 
 wherein transmitting the set-top box turn-on signal to the set-top box through the home wireless network comprises: 
 transmitting the set-top box turn-on signal to the set-top box periodically through the home wireless network according to a predetermined frequency; 
 determining by the set-top box, whether the set-top box turn-on signal transmitted by the intelligent mobile terminal is received within a predetermined time interval, 
 when the set-top box turn-on signal is not received within the predetermined time interval, executing a turn-off operation, and transmitting a television turn-off signal to the television. 
 
     
     
       2. The method according to  claim 1 , wherein the home wireless network is a home Wireless-Fidelity (Wi-Fi) network or a home Bluetooth (BT) network. 
     
     
       3. The method according to  claim 2 , wherein transmitting the television turn-on signal to the television comprises:
 transmitting the television turn-on or turn-off signal to the television through a High Definition Multimedia Interface (HDMI). 
 
     
     
       4. The method according to  claim 2 , wherein transmitting the television turn-on signal to the television comprises:
 transmitting, by the set-top box, a Wi-Fi or BT television turn-on or turn-off signal to an infrared transmitter through the Wi-Fi or BT network, and converting, by the infrared transmitter, the received Wi-Fi or BT television turn-on or turn-off signal into an infrared television turn-on or turn-off signal, and then transmitting the infrared television turn-on or turn-off signal to the television. 
 
     
     
       5. The method according to  claim 1 , wherein the home wireless network is a home Wireless-Fidelity (Wi-Fi) network or a home Bluetooth (BT) network. 
     
     
       6. The method according to  claim 5 , wherein transmitting the television turn-on signal to the television comprises:
 transmitting the television turn-on or turn-off signal to the television through a High Definition Multimedia Interface (HDMI). 
 
     
     
       7. The method according to  claim 5 , wherein transmitting the television turn-on signal to the television comprises:
 transmitting, by the set-top box, a Wi-Fi or BT television turn-on or turn-off signal to an infrared transmitter through the Wi-Fi or BT network, and converting, by the infrared transmitter, the received Wi-Fi or BT television turn-on or turn-off signal into an infrared television turn-on or turn-off signal, and then transmitting the infrared television turn-on or turn-off signal to the television. 
 
     
     
       8. An intelligent mobile terminal, comprising: a detection component and a transmission component, wherein
 the detection component is configured to detect whether the intelligent mobile terminal is connected to a home wireless network, and when it is detected that the intelligent mobile terminal is connected to the home wireless network, notify the transmission component to execute an operation of transmitting a set-top box turn-on signal to a set-top box; and 
 the transmission component is configured to transmit the set-top box turn-on signal to the set-top box through the home wireless network according to the notification from the the detection component; 
 wherein the transmission component is configured to transmit the set-top box turn-on signal to the set-top box periodically through the home wireless network according to a predetermined frequency; 
 when the set-top box turn-on signal is not received within the predetermined time interval, execute a turn-off operation; and notify the transmission component to execute an operation of transmitting the turn-off signal to the television. 
 
     
     
       9. A set-top box, comprising: a turn-on component, a transmission component, and a turn-off component, wherein
 the turn-on component is configured to execute a turn-on operation according to a set-top box turn-on signal transmitted from an intelligent mobile terminal; and 
 the transmission component is configured to transmit a television turn-on signal to a television according to the set-top box turn-on signal transmitted from the intelligent mobile terminal and to transmit a turn-off signal to the television according to receiving a notification from the turn-off component; 
 the turn-off component is configured to:
 determine whether the set-top box turn-on signal transmitted from the intelligent mobile terminal is received within a predetermined time interval; 
 when the set-top box turn-on signal is not received within the predetermined time interval, execute a turn-off operation; and 
 notify the transmission component to execute an operation of transmitting the turn-off signal to the television.
